我正在为 Google Cloud Vision API 编写“标签检测”教程。
当我像这样将图像传递给命令时,我希望返回一些 json 告诉我图像中的内容。
但是,我却收到了这个错误。

这里发生了很多事情。
但项目 API 已启用。
所以这是错误信息的一部分是错误的。
似乎“最新版本的 oauth2client v2.0.0 发生了变化,这破坏了与 google-api-python-client 模块的兼容性”。

我应用了这个修复...
pip install --upgrade git+https://github.com/google/google-api-python-client
应用此修复程序后,我得到的错误更少了......

看起来这个错误信息: “找不到记录器“oauth2client.util”的处理程序 实际上掩盖了更详细的警告/错误消息 并且我可以通过添加此代码来查看更详细的信息...
import logging

所以不,我卡在了这条错误信息上:
警告:oauth2client.util:build() 最多接受 2 个位置参数(给定 3 个)
有人建议可以通过使用命名参数而不是位置符号来避免此错误。
https://stackoverflow.com/a/16643215/2341218
但是,我不确定我到底应该在哪里做这个改变。
我实际上并没有在代码中看到 oauth2client.util:build() 函数。
这是谷歌代码(稍作修改):
😈 >cat label_request.py
import argparse
import base64
import httplib2
from apiclient.discovery import build
from oauth2client.client import GoogleCredentials
import logging
logging.basicConfig()
def main(photo_file):
'''Run a label request on a single image'''
API_DISCOVERY_FILE = 'https://vision.googleapis.com/$discovery/rest?version=v1'
http = httplib2.Http()
credentials = GoogleCredentials.get_application_default().create_scoped(
['https://www.googleapis.com/auth/cloud-platform'])
credentials.authorize(http)
service = build('vision', 'v1', http, discoveryServiceUrl=API_DISCOVERY_FILE)
with open(photo_file, 'rb') as image:
image_content = base64.b64encode(image.read())
service_request = service.images().annotate(
body={
'requests': [{
'image': {
'content': image_content
},
'features': [{
'type': 'LABEL_DETECTION',
'maxResults': 1,
}]
}]
})
response = service_request.execute()
label = response['responses'][0]['labelAnnotations'][0]['description']
print('Found label: %s for %s' % (label, photo_file))
return 0
if __name__ == '__main__':
parser = argparse.ArgumentParser()
parser.add_argument(
'image_file', help='The image you\'d like to label.')
args = parser.parse_args()
main(args.image_file)
最佳答案
我遇到了完全相同的问题,我只是解决了执行此代码行(您必须安装 gcloud):
gcloud auth activate-service-account --key-file <service-account file.json>
然后:
$ export GOOGLE_APPLICATION_CREDENTIALS=<path_to_service_account_file>
希望对您有所帮助!
